Post-Project Reviews are mainly used as a tool to improve organisational learning (Busby, 1999; von Zedtwitz, 2002). However, post-project reviews can also be used as a tool to identify new market potential and to hand over technical knowledge from technical to marketing personnel (von Zedtwitz, 2002). This paper presents the findings of a research project on the improvement of commercialisation at TNO Industrial Technology. After the problem analysis, post-project reviews are introduced as one of the potential solutions to improve the commercialisation of knowledge creation projects.
